The causes of these problems could be damage to the foam, corrosion, and deposition. The most common cause of corrosion is because of the electrochemical reactions in the vicinity of the walls of the boiler drum. The cause of foaming is A high amount of dissolved solids. This results in steam carrying across impurities. It also causes deposition of the impurities onto the turbine’s blade and shell. Deposition can be result of high temperatures. It results in the blades and shell to become encrusted by carbonates and phosphates. This could cause tube constriction and collapse.
Treatments for corrosion include demineralization, deaeration, desulphurization and drum wall plating and altering pH. Filtration, foaming as well as condensate polishing demineralization are effective. Water purification, carbonate removal as well as condensate polishing are all effective for deposition. They are complicated that are worthwhile to study if want to understand how boiler water treatment functions. 5jrevzfnuk.
